Hepatocellular carcinoma with concomitant hepatic angiomyolipoma and cavernous hemangioma in one patient

Figure 3 Histological features of the tumors in this case. A: The HCC, showing a poor- to moderately-differentiation level, was demarcated from the surrounding liver tissue with a relatively clear boundary (HE staining, magnification × 50); B: A tumor emboli of HCC was found in a blood vessel located outside of the HCC mass (HE staining, magnification × 200); C and D: The AML component was composed of smooth muscle cells, adipose cells and blood vessels. The 0.3 cm white nodule in the middle of the AML was an HCC nodule with the same composition as the 9.0 cm HCC mass (C: HE staining, magnification × 10; D: HE staining, magnification × 200); E: The cavernous hemangioma areas were composed of large thin-walled vascular spaces, lined by a monolayer flat endothelial cells (HE staining, magnification × 50). HCC: Hepatocellular carcinoma; AML: Angiomyolipoma; HE: Hematoxylin and eosin.
